On sale now! The Frost ($16) is a decent single edge design for it's low price, and the blade is of high quality (made in Sweden, NOT China!), but it does take some ingenuity to mount one on your pfd. The sheath just has a snap button strap that wraps around the bottom of the knife handle - certainly not the best design for retaining a knife. We will be discontinuing these in the near future when we run out of our current stock. These were popular many years ago, but not so much anymore. Specify red or yellow and please remember we have a $25 minimum order.
